Review - iPhone 3G - Part 4

On the superior part, to the right, there’s the small button that functions both as a screen lock and a turn on/off button. On the left part there’s the mini-jack plug for the headphones that compared to the normal iPhone, allows the usage of third-party headphones.

At the superior border we can also find the small case where the SIM card will be placed. Using the accessory that is supplied with the pack, users can unlock the mechanism that keeps the cover in place in order to place the SIM in the phone. On the left side of the phone, there’s a slide switch that allows users to silence the telephone’s ringtones. Not far from it, two buttons are responsible for adjusting the volume of any sound.
